Why do you think an FRH doesn't come with water already in it?
Because then there would be no reaction.
Why doesn't FRH come with water in it?
Maybe because the chemicals might be ruined or not considered "chemicals" anymore. As you all know, water purifies things; it doesn't destroy things. Chemicals are in the FRH. Water would purify it.
Why does a flameless ration heater in the MRE NOT come with water already in it?
Because adding water to it activates it. It would be pointless to pack a previously activated ration heater in MREs. That, and the one thing service members can pretty well count on, even in combat situations is water for their canteen or Camel Back hydration system. Additionally, the MRE pouch is a tough, sealed, plastic bag, not easily opened without a knife. The FRH is essentially a battery when water is added (see the chemical reaction between magnesium and iron powder, salt, and water). One of the byproducts of activation of the FRH is hydrogen gas, which anyone who has seen the video footage of the Hindenburg Disaster knows is extremely volatile. Imagine the service member sitting on a rock in the field, preparing to enjoy his nutritious Meal, Ready-to-eat, puffing away on his Lucky Strike, when he drives his M7 bayonet into the bloated pouch containing his FRH with the water conveniently added by the manufacturer. Now imagine the expression on the faces of the group of insurgents a klick or so away when they hear a sharp crack, look up to see a small white mushroom cloud over the next hill, and get a whiff of burnt GI crewcut. That, kids, is why the flameless reaction heater doesn't come with water already inside.
Why does iron and sodium included FRH?
Iron and sodium are included in FRH (Flameless Ration Heaters) because they undergo an exothermic reaction when activated by water, generating heat to warm up the food in the ration pack. Iron reacts with oxygen in the presence of water to produce heat, while sodium helps initiate and catalyze the reaction to speed up the heating process.
Are there small or large pieces of magnesium in FRH?
There are small pieces of magnesium in Flameless Ration Heaters (FRH). They are typically in the form of a thin strip or coil that reacts with water to produce heat for heating up food items.
Why do you think they are included in an FRH?
Items like fuel canisters and heaters are included in an FRH (Field Ration Heater) to provide soldiers with the means to heat their food quickly and efficiently in the field, ensuring they have a hot meal even when traditional cooking methods are not available. This helps to maintain morale and provide essential nutrition to troops in challenging environments.
Why is it important that the reaction in an FRH be fast?
A fast reaction in a Fast-Reacting Hydride (FRH) is important because it allows for quick response times and rapid release of hydrogen when needed. This is crucial for applications where immediate hydrogen uptake or release is required, such as in hydrogen storage and fuel cell systems. A slow reaction in an FRH can limit its effectiveness and efficiency in these applications.
Why are iron and sodium chloride included in an FRH?
Because it is a fast reactant and works and warns up within the 15 mins.
What is the airport code for French Lick Municipal Airport?
The airport code for French Lick Municipal Airport is FRH.
Where is flemings left hand and right hand rules are used in operation of induction motor?
For conventional flow (plus to minus) FLH rule is for motor action, and FRH rule is for generator action. So you can use FRH rule to determine the direction in which voltages are induced into the rotor by the rotating magnetic field, then use FLH rule to determine the direction in which the resulting forces, due to the rotor-bar currents, will act to rotate the rotor.

Who made first balloon flight in what year did the flight take place?
The first balloon flight was made by the Montgolfier brothers, Joseph-Michel and Jacques-Étienne, in 1783. The flight took place in France and marked the beginning of manned flight in a hot air balloon.
